1. The texture is unsuitable and poorly aligned. Texture the sides first, using alt-right click to instantly align and texture. Then do the 'steps' themselves, the verticals. Then alt-right click the flats.

the hallways themselves seem to be arbitrary that you could put nothing into them to give them relevance and meaning. they should at least look like they are going somewhere relevant...difficult to explain what I mean, but usually hallways are in the middle of rows of offices or something.
